What Can I Do When the ESN Is Repeated During License Application If eSight Is Deployed on a FusionCompute VM

Question

What can I do when the ESN is repeated during license application if eSight is deployed on a FusionCompute VM?

Answer

Before eSight V300R005, the ESN generated by the MAC address of the network adapter on the physical server or VM is used to apply for a license. The ESN must be unique.

Because the MAC address can be manually changed using the management tool and the FusionCompute allocates virtual MAC addresses for virtual network adapters, the virtual MAC addresses may be the same for network adapters on physical servers or VMs where eSight is deployed at different sites. As a result, the license application fails.

In this case, refer to "Operation and Maintenance > Virtual Machine Management > Modifying Advanced Properties of a VM > Modifying VM NIC Attributes" in the FusionCompute V100R005C10 Product Documentation and change the MAC address of the FusionCompute VM where eSight is deployed to a globally unique value.

NOTE:

Ensure that the changed MAC address meets the following requirements:

  • It is unique in the current FusionCompute system.
  • It is unique across all FusionCompute systems at the current site, and does not conflict with the MAC address of any physical or virtual network adapter.
  • It complies with site planning, and the globally unique ESN does not conflict with others at other sites or influence the deployment of eSight on physical servers or VMs.

Sample: Locating the Fault That Causes a Slow Operation of eSight

This topic describes how to locate the fault that causes a slow operation of eSight.

Applicable Product and Version

eSight V300R005C00 or later

Scenario Description

A user complains that VMs with IP addresses 10.137.63.201 and 10.137.63.202 are running very slowly.

Procedure
  • Locate the fault that causes a slow operation of the VM with IP address 10.137.63.201.
  1. Click the Search icon in the upper right corner and enter IP address 10.137.63.201 in the search text box.
  2. Select the VM you want to view and click it to access the VM resource manager.
  3. Choose Details > Basic Information in the navigation area on the left to verify static configurations of the VM.
  4. Choose Details > Alarm List in the navigation area on the left to check alarms of the VM. Ensure that all alarms of the VM have been handled.
  5. Choose Details > Physical Topology in the navigation area on the left to verify the connection between the host where the VM resides and the external network.
  6. Choose Details > Component Topology in the navigation area on the left.
  7. Click in the upper left corner of the topology to enable the topology to display the CPU usage and memory usage of the VM.
  8. After a moment, the CPU usage reaches up to 95%, while the memory usage is only 20%. Some services on the VM consume excess CPU resources, causing a low operation of the VM.
  9. Disable the services that consume excess CPU resources or allocate more CPU resources to the VM.

  • Locate the fault that causes a slow operation of the VM with IP address 10.137.63.202.
  1. Click the Search icon in the upper right corner and enter IP address 10.137.63.202 in the search text box.
  2. Select the VM you want to view and click it to access the VM resource manager.
  3. Choose Details > Basic Information in the navigation area on the left to verify static configurations of the VM.
  4. Choose Details > Alarm List in the navigation area on the left to check alarms of the VM. Ensure that all alarms of the VM have been handled.
  5. Choose Details > Physical Topology in the navigation area on the left to verify the connection between the host where the VM resides and the external network.
  6. Choose Details > Component Topology in the navigation area on the left.
  7. Click in the upper left corner of the topology to enable the topology to display the inbound/outbound rate of the VM network adapter and the inbound/outbound bandwidth usage of the physical interface.
  8. After a moment, the inbound/outbound rate of the VM network adapter is still lower than 100 kbit/s, but the inbound/outbound bandwidth usage of the physical interface already exceeds 90%. Other VMs on the physical interface occupy excess bandwidth.
  9. Choose Details > Other VMs on Same Host in the navigation area on the left.
  10. Observe the inbound/outbound rates of all VM network adapters on this page and find that the VM network adapter named VM_3 encounters an abnormal inbound/outbound rate. Click the name of the VM to access its resource manager.
  11. Choose Details > Component Topology in the navigation area on the left to view the statistics of key performance counters of the VM.
  12. After a moment, the inbound/outbound rate of the VM network adapter reaches up to 10 Gbit/s. The VM occupies excess bandwidth, so other VMs on the physical interface cannot obtain sufficient bandwidth.
  13. Choose Details > Network Traffic Analysis in the navigation area on the left.
  14. Find the chart with abnormal traffic and click the resource link to access the Traffic Monitor page, on which you can view detailed traffic statistics of sessions and applications.
  15. Disable sessions or applications that occupy large bandwidth.
